I remember when I was in my 20’s I was dating a lovely pregnant girl just like her who was pregnant by another man. One time I was fingering her and enjoying her delicious pregnant pussy juice when I felt her cervix with my finger and decided to shove my pointer finger as deep as I could into her cervix without any notice. Once I did that she yelled at the top of her lungs. Not long after I found out she was not pregnant anymore. I still feel bad but it was an interesting experience.
